I feel so flustered and it has been one of those days.
I work in various places so was driving to a place I had never been before and I ended up on a road with building work so temporary traffic lights were there. There was probably about 4 cars ahead of me stopped on the red light and a huge lorry.
2 minutes into waiting, the guy in the lorry waved his hand at me as if to say "go" and kept waving, I ignored and then his waving started getting more frantic.
So I drove around his lorry and the car behind me followed, next thing i'm getting beeped at by every car and realise that i shouldn't have gone and told to pull in by one of the builder. The car behind me explained and I explained, but I presumed this lorry was working with the builders and the light was on green and nobody moved so when he waved i thought to go.
I feel like such an idiot.
